GIVING SPECIALISTS SHARPER VISION


G-ray wants to enhance health in the world by helping doctors in their diagnostic capacities. Specialists thrive to produce the best diagnostic to offer patients the most suited medical treatments.

However, existing technologies at hand are expensive, still with limited precision or expose patients and specialists to risks. G-ray offers a new technology that makes medical imaging solutions more precise, more secure, more readable and more accessible.

G-ray is a prime example of how science-led companies unlock new opportunities. Having set out to disrupt x-ray medical imaging through the unique, prorietary use of Si-Ge absorbers, G-ray struck upon a wafer-to-wafer direct covalent bonding approach that opened a broad range of applications covering a wide range of industries. The upshot is that G-ray is now positioned to bring several breakthrough innovations to market, combined in a unique platform.

LESS EXPOSURE.SAFER FOR PATIENTS AND PROFESSIONALS.

We will expose patients and specialists to a much reduced radiation dose absorption, enabling health risk minimization.

As germanium has a higher atomic number than the widely used silicon, its contribution to our unique Si-Ge absorber of x-rays enables excellent resolution while cutting the exposure of patients and physicians to ionizing radiation. The columns of Si-Ge are reminiscent in form and function to photoreceptor cells in the eye.

The combination of ultra-high sensitivity and excellent energy and micrometric resolution enabled by Si-Ge remains key to G-ray’s plans. It forms the bedrock of the first planned application of the sensor technology, which will address the need in mammography to differentiate between types of calcification. Other applications will also be considered, including medical navigation systems and in vitro diagnostics. Yet, in overcoming the problems that blocked the advance of the concept to market, G-ray also discovered techniques with applications far beyond mammography.

BREAKTHROUGH X-RAY TECHNOLOGY TO IMPROVE HEALTH

A powerful combination for the ultimate monolithic detector

G-ray’s original idea was to grow germanium crystals directly onto CMOS (complementary metal-oxide-semiconductor) processed silicon wafers. However, CMOS is ill-suited to the temperatures needed for epitaxy, the process of growing a layer of crystal on a crystalline substrate.

This led G-ray to explore low temperature covalent wafer bonding. Rather than growing Si-Ge directly on CMOS processed wafers, G-ray sought to separate the two processes. By performing epitaxy away from the CMOS wafer, G-ray could use the optimal conditions for both components. Then, through direct low-temperature wafer-to-wafer bonding, G-ray created a monolithic CMOS integrated pixel-array detector that is free of bump bonding and through-silicon vias (TSVs).
